SPECIFICATION forming part of Letters Patent No. 241,687, dated May 17,1881.

Application filed February 17, 1881. (No model.) i

To all whom it may concern:

Be it known that I, CLINTON MENDENHALL, a citizen of the United States,residing at Martinsburg, in the county of Berkeley and State of WestVirginia, have invented a new and useful Improvement in Cultivators, ofwhich the following is a full, clear, and exact description, referencebeing had to the annexed drawings, forming part of this specification.

The object of my invention is to provide a cultivator which shall beadapted for cultivatin g different kinds of grain, and for use uponstony or stumpy ground.

My invention consists in a wheeled frame, having lugs and inclines onits forward end, and a system of levers and shafts, by means of whichthe plows may be lifted out of the ground, as hereinafter described andclaimed.

In the accom panying drawings, Figure 1 represents a plan view of myinvention without the levers for manipulating the plows; Fig. 2, a sideelevation, showing said levers; Fig. 3, detail views of the plow andfoot-piece; and Fig. 4: a rear view of the cultivator, showing the leverfor guiding the tongue, the plows not being shown.

Referring to the drawings, the square or rectangular frame A issupported upon the two wheels B, and provided with a tongue, (J,pivotedto its forward part at a, so as to allow an oscillating movement. withtwo parallel shafts or rods, a, extending from side to side, to whichare secured two sets of foot-pieces, b, for carrying the plows c. Thesaid foot-pieces are provided with a series of grooves, 1), across therear portion of their upper ends, into which the said rods are adjustably held by bolts 71 curved at their rear ends, so as to form a restfor the same.

At the lower ends of the foot-pieces are attached plows or shoes 0, madeof a nearlysquare piece of metal bent diagonally in order that it maybeused reversibly. These plows are so arranged that those in the rearshall The frame is provided pass between the furrows made by the forward5 ones, whereby the soil may be completely broken, or by removingcertain of the plows the cultivator may be adapted for cultivating corn,&c.

To the forward part of said foot-pieces are pivoted lovers 0, havingtheir forward ends loosely secured to a cross-rod, M, which rests uponwedges or inclines a on the forward part .of the frame, and by means oflugs a limits the backward movement of the plows. The said rod restsupon the wedges a near their points, and is connected, by means of ashort lever, e, to the lower end of a lever, 0 pivoted at its center tothe front of the frame, and having its upper end connected to thehandlever c by lever 6 so that when the hand-lever is brought to anupright position the said rod will slide up the inclined surface of thewedge and draw the plows forward out of the ground to enable them topass obstructions. 6 5

A means for guiding the cultivator is provided in the oscillating tongue0, which ispivoted to the forward part of the frame, and has its rearend connected, by means of lever f, to an upright hand-lever,f, which ispivoted to the frame. By this means the cultivator can be used along theside of a hill, or for cultivating crooked rows of corn, without theusnalinconvencies in such cases.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a cultivator, the wheeled frame A, having lugs a and parallelinclines a at its forward end, in combination with cross-rod a levers e,e, 0 c and e, shafts a, foot-pieces b, and plows c, substantially asshown and described.

CLINTON MENDENHALL.
